Vladimir suggested I remove the reinitialisation check so that local
configuration can overwrite global - which is a reasonable
requirement. Maybe it should ignore reinitialisation without values,
and be an error if it's reinitialised with values after being used for
anything else  - assuming no actions are performed by configuration
files, that we can detect use and it isn't too hairy to implement.

This is really going to need a warning (or error) for any Jamfiles
which don't have the necessary using directives (or whatever), even if
they are already configured. Is that possible?
